CATCH FASTENER WITH LOCKING DEVICE FOR PINS, BROOCHES, ANI) THE LIKE.

Application filed .Tune 8, 1920. Serial No. 387,333.

To all whom t may concer/a.' within said box 7 by any suitable way, forBe it known that l, GUs'rAvn AN'roiNn instance by means of a stud 8 onits base,

RENAULT, a citizen of the French Republic, retaining a small helicalspring against a residing at Paris, Rue Reaumur 37, Seine, smallshoulder 10, and also by means of two in State of France, have inventedcertain lateral feathers ll-lQ, fastened on box 7, 50 new and usefulImprovements in Catch corresponding with two notches 13 14, on Fastenerswith Locking Devices for Pins, the strap. Said notches are vsomethingBrooches, and the like; and do hereby dewider than the feathers, thusproviding for clare the following to be a full, clear, and the requiredamount of clearance.

Many kinds of jewelry articles are used, The outside surfaces of thejaws l5 l6 such as bi'ooches, hatand tie-pins, etc., are oblique shaped;the inside surfaces of i5 which consists of two parts, the first partSaid jaws are curved, according to the round 70 being the properlycalled pin, the second Oi Oval Shape of holes 2 3 on the pin. parthaving the shape of a sheath or case, Both parts 1 and 7 beingseparated, asin which the point of the first part is located. sinne theuser of such a device wants to put After the pin has been put throughthe tisand fasten the pin l into case 7, it may be sue, on which thejewel is to be fastened, the easily done by putting pin l into hole 17and 75 first part or pin is usually secured in the forcing said pinthrough the jaws of strap il, second part by means of a transverse slotbut the pull exerted upon the pin will push (cut in the body of the pin)and a small back the said strap, until the resistance of tenon connectedwith a small flat spring, rivthe spring 9 stops the motion. cted on thebody of the second part.

The system above described is able to be used for many variousappliances, namely as a point-cover or protector for hat-pins.

What I regard as new and desire to secure by Letters Patent is:

l. A pin having a pocket, a yieldable catch normally urged into saidpocket and adapted to be disengaged from the pocket upon a rotarymovement ot' the pin, and a case for the catch adapted to guide thecatch into the pocket upon a longitudinal movement of the pin and catchin the direction to remove the pin from the case.

2. A device of the character described comprising al pin` having a pairof pockets at diametrically opposite points with walls roundedlongitudinal andl circumferential, the portions of the pin between theopenings being left blank, a strap of resilient material having jaws atits tree ends adapted to yieldably engage in said pockets and guided bythe curved walls of the pockets out of engagement therewith when the pinis turned, and a case receiving the strap and acting to force the jawsmore firmly into the pockets on withdrawing movement olr the pin.

3. In combination'with a pin having a lateral pocket, a yieldable catchnormally urged in the pocket and adapted upon a rotary movement of thepin to be disengaged from said pocket, a case to receive the pin and tohold the catch, said case and catch having' mutually tapered wallsadapted to guide the catch into the pocket automatically upon an axialmovement of the pin in a direction to withdraw the pin from the case,A

and yieldable means for independently urg ing the catch against thetapered wall of the case.

In testimony whereof I ailiX my signature in presence of two witnesses.
